回答1:

You need an URL and call toExternalForm in order to load a css file into your project.
Use the ClassLoader for that:

scene.getStylesheets().add(getClass().getResource("/style.css").toExternalForm());

For those who can't find css the way from accepted answer use classLoader:

getClass().getClassLoader().getResource("css/style.css").toExternalForm()

If you use maven it will find your css under resources/css/ dir.

Simply add package name with .css file.

Your code will look like this:

scene.getStylesheets().add("sample/appCssFile.css");
